We all know that the Cavalier Breed is struggling to Survive at the Moment because of mainly their SM and MVD Health Problems.
The Future of a Breed is not about how many Diseases the Breed has ,but the Severity and their Frequency within the Population .
We know the MVD Figures as given by the Researchers ,that 50% of Cavaliers of Cavaliers have a Heart Murmur at 5-6 Years of Age , and this is no better than it was 18 years ago.
That over 90% of Cavaliers have CM .
Also 85 Whelps who were Researched All had CM.
The Problem for our Cavaliers could be, that there are maybe Too Few Clear Cavaliers to Breed from .
It has to be remembered that Genetic Carriers identified by DNA Testing ,should be being kept IN the Cavaliers' Breeding Programs ,Initally to keep Genectic Diversity as High as Possible .
This means that Cavalier Carriers who are Clear of SM and MVD can be Mated to other Cavalier Carriers who are also Clear , these Matings will only Produce Off-Springs who don't have SM or MVD or the Cavalier Puppies will be Carriers but won't have SM or MVD.
The Big Problem for the Cavalier Breed ,this information is only for the Cavaliers if SM and MVD is Identified with a Single Gene Recessive Mutation.
The Draw-Back for our Cavaliers ' SM and MVD Health Problems to Over-Come,that they, as far as I am aware ,both those those Diseases can only be Assessed by Phenotypic Screening Tests ,and that even a Good Result is NO GUARANTEE that the Sires and Dams are not going to Produce Affected Cavalier Puppies.
I know that MVD Cardiologists who are Researching the MVD Problem in our Cavaliers are saying that it is Very Likely that there are Many Cavalier Carriers of the MVD Genes.
Because it is known that over 90% of Cavaliers have CM ,there cannot be many Cavaliers who are not Carriers of the CM Genes.
To complicate the our Cavalier Breeds' SM and MVD Problem further ,we don't even know yet ,how SM, CM and MVD is Inherited.
